Purpose To study the changes in intraocular pressure (IOP) and aqueous flare in eyes with multiple evanescent white dot syndrome (MEWDS) during the disease course. Study design Retrospective observational study. Methods Twenty-one patients with unilateral MEWDS were retrospectively evaluated. IOP values were compared between the affected and fellow eyes 2 weeks, 1 month, and 3 months following disease onset in 17 patients, and within 7 days from disease onset in 11 patients. Aqueous flare values measured using a laser flare-cell meter in ten eyes between 1 weeks and 1 month from disease onset were compared between the affected and fellow eyes. Results IOP values were significantly lower in the affected eyes than in the fellow eyes at both 2 weeks ( P =0.002) and 1 month from disease onset ( P =0.02). However, IOP values of affected eyes did not show significant differences from the fellow eyes within 7 days (( P =0.11) and 3 months of onset ( P =0.30). Aqueous flare values were significantly increased in the affected eyes compared to those in the fellow eyes ( P =0.010) and significantly correlated with IOP values (r=−0.67, P =0.035). Conclusion IOP values mildly decreased in association with aqueous flare values in the acute phase in eyes with MEWDS.
